Y BOTTLE-stoppen.

SPECIFICATION forming part of Letters Patent No. 469,095, dated February 16, 1892.

Application filed August 5, 1891. Serial No. 401,808- (No model.)

To a/ZZ whom it may concern:

Be it known that I, FERDINAND SCHMIDT, manufacturer, of Berlin, in the Kingdom of Prussia and German Empire, have invented new and useful Improvements in Bottle-Stoppers, of which the following is a specification, reference being had therein to the accompanying drawings.

vwhich- Figure I is a side elevation of a bottle provided with my improved bottle-stopper, illustrating the position of a hand in securing the stopper. Fig. II is a similar view illustrating the position of a hand in releasing the stopper. Fig. III is a vertical longitudinal section of the stopper at right angles to that shown in Figs. I and- II.

In stoppering bottles and other vessels accordin g to the invention hereinafter described the stopper proper consists of two parts ct and b, between which is arranged a ring c of india-rubber. A screw-threaded bolt d is passed through the part a. and ring c and is screwed into the lower part b and turns in the part CL of the stopper. Above the part ct is placed a bearing-disk e, upon which the wedge f bears.

This wedge f can be moved within a slot d',

formed in the bolt d, and bears against the upper part thereof, being further provided at each end with a disk h h, riveted thereon and serving as pressure-pieces to close and open the stoppering` device, while at thesame time preventing the wedge from leaving the bolt d.

z is a ring at the upper end of the bolt to facilitate the Withdrawal and insertion of the stopper. hen applying this stoppering device to a receptacle-such as a bottle, for in- 45 stance, Fig. I-the stopper is inserted in the neck of the bottle and the ring c is compressed or expanded as lthe wedge is pressed forward in the direction of the arrow, whereby the wedge comes to bear against the disk o e by means of its straight under surface, and thus lifts the bolt with the part b and presses the ring c upon the part a, and presses the ringo against the neck of the bottle.

To release the device the wedge is moved in the direction of the arrow, Fig. II, and the stopper is withdrawn. Each time the wedge is pushed in the'direction of the arrow, Fig. I, the india-rubber ring is compressed.

What l claim, and desire to secure by Let- 6o ters Patent of the United States, is

A bottle-stopper consisting'of a bolt having a screw-threaded lower end and. a longitudinal slot in its upper end, the lower part of the body surrounding the screw-threaded portion of the bolt, the compressible and expansible ring surrounding the bolt and located above the lower part of the body, the upper part of the body surrounding the bolt-and located above the ring, and the wedge Working 7o FERDINAND SCHMIDT.
